I have noticed, some DTS movie tracks play back sounds resembling stuttering, but only on passthrough mode. The stuttering only occours in the lower frequencies of the sound (trumpets are clear, while voices and low frequency sounds stutter). Most other movies I have playback DTS just fine. But as I wrote, the same DTS tracks I tested works fine in other players or in non-passthrough mode.
I cannot say if the problem occours on any other systems, as only one of my players can be setup in passthrough mode.
I can provide a sample, if you tell me where to upload it?
